Diabetes is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. Ask anyone with the condition and they will tell you: using a spring-loaded needle to prick their fingers monitor blood glucose (i.e.sugar) levels several times a day is painful procedure.

Researchers from the University of Washington (UW) and Microsoft Research Connections are working together to develop a non-invasive, technological solution that promises to improve both the health and overall quality of life for people with diabetes: a contact lens that, instead of correcting vision, monitors blood glucose levels.
